The Cedar River is a 338-mile-long (544 km) river in Minnesota and Iowa. It is a tributary of the Iowa River, which flows to the Mississippi River. The Cedar River takes its name from the red cedar (Juniperus virginiana) trees growing there, and was originally called the Red Cedar River by the Meskwaki. The first Mississippi steamboat reached Cedar Rapids, Iowa in 1844, and during the next decade, the Red Cedar (as it was still called) was an important commercial waterway. The surrounding region is known officially as the Cedar River Valley, though it is more commonly referred to simply as the Cedar Valley. The stream is young geologically, and only in places where the glacial material has been removed is the underlying bedrock exposed.

The Community Building, also known as Columbus Junction School 1882-1920, is a historic building located in Columbus Junction, Iowa, United States. It houses the Columbus Community Heritage Museum, and it was listed on the National Register of Historic Places in 1973. The building was constructed as a school and served the function from 1882 to 1920. After being renovated by the Works Progress Administration it served as a gathering place for various community functions. The building was damaged in a fire in the 1960s and the first floor was restored to serve as a library and meeting room. Subsequently, the building has been renovated into a community history museum. The two-story brick structure is basically a large block with a wing on the south side. The entire structure is capped with a hip roof. The Vernacular style building features a prominent belfry, which is a reconstruction. The building's brick exterior appears to be a better quality than what was generally manufactured in Columbus Junction so it is assumed it was imported from elsewhere.
